L7905CV from STMicroelectronics, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated negative output voltage pin; for L7905C, VO = -4.8 to -5.2 V at TJ=25°C, rated for output currents up to 1.5 A with internally limited current and thermal/SOA protection. |
| 2 | IN | power_in | Unregulated negative DC input voltage pin; absolute maximum DC input voltage is -35 V for output voltages of -5 to -18 V, with input filter capacitor (2.2 µF) recommended close to the device. |
| 3 | GND | power_in | Common/ground reference pin for the regulator, referenced in the test circuit with input and output decoupling capacitors returned to this node. |
